Flow of Energy

Flow of Energy

B.12C:

analyze the flow of matter and energy through trophic levels using various models, including food chains, food webs, and ecological pyramids 

Multiple Choice

All energy in an ecosystem comes from the sun. This energy is passed through the ecosystem as organisms eat other organsims.

• Ominvores

• Herbivores

• Detritivores

• Flow of energy

Multiple Choice

Organisms that produce their own food mostly through photosynthesis (producers). Examples are plants and algae.

• Ominvore

• Detritivore

• Heterotroph

• Autotroph

Multiple Choice

During ____________, _____________ convert light energy into the chemical energy in sugar molecules. 

• chemosynthesis, consumers
• chemosynthesis, producers
• photosynthesis, producers

Multiple Choice

Organisms that get their energy and nutrition from other organisms (consumers).

• Heterotroph

• Autotroph

• Decomposer

• Detritivore

Multiple Choice

Animal that gets its energy and nutrition from eating plants.

• Parasite

• Herbivore

• Carnivore

• Omnivore

Multiple Choice

An animal that eats other animals is a....

• carnivore

• omnivore

• herbivore

• decomposer

Multiple Choice

An organism that eats both plants and animals are know as a

• Carnivore

• Omnivore

• Herbivore

• Decomposer

Multiple Choice

Heterotrophs that “clean up” the ecosystem by eating dead and decaying organisms.

• Autotrophs

• Herbivores

• Ominvores

• Detritivores

Multiple Choice

Heterotrophs that get energy and nutrition from dead or decaying organisms or their waste products and recycle nutrients back to the ecosystem.

• Producer

• Trophic

• Decomposer

• Autotroph

Multiple Choice

All of the following are consumers except

• Autotrophs

• Herbivores

• Heterotrophs

• Omnivores

Multiple Choice

The fourth trophic level where animals eat secondary consumers or below.

• Herbivore

• Autotroph

• Tertiary Consumer

• Tertiary Producer

Multiple Choice

The third trophic level where the animals eat herbivores.

• Abiotic Factor

• Biotic Factor

• Secondary Consumer

• Secondary Producer

Multiple Choice

Herbivores--The second trophic level where herbivores eat the primary producers.

• Detritivores

• Autotrophs

• Producers

• Primary Consumers

Multiple Choice

Autotrophs--The bottom trophic level where all organisms produce their own food, usually by photosynthesis.

• Trophic Levels

• Producers

• Ominvores

• Herbivores

Multiple Choice

Matter is passed up the ecological pyramid in a similar way to energy but recycled by decomposers and detritivores. This Biomass pyramid roughly follows the 10% rule as well.

• Producers

• Flow of matter

• Ecological Hysteria

Multiple Choice

Only 10% of the energy is passed on from one trophic level to the next. 90% is lost as heat due to cellular respiration or waste.

• Tertiary Consumer

• Biotic Factor

• Abiotic Factor

• 10% Rule

Multiple Choice

Which organisms in the diagram have the most energy to give to other organisms?

• Cattails and Marsh Grass

• Hawks and Snakes

• Crickets and Grasshoppers

• Shrews and Frogs

Multiple Choice

What is a food chain?

• A chain that shows how heat passes from organism to organism.

• A way of showing how matter and energy pass from one organism to another.

• A representation of all the predator-prey relationships in a community.

Multiple Choice

What type of organisms are the first step in a food chain?

• Consumers

• Predators

• Producers

Multiple Choice

Why is the insect a consumer?

• It is eaten by a mouse.
• It can make its own food.
• It eats the plant.

Multiple Choice

A food web is made up of

• one food chain.

• only producers.

• many different food chains.

Multiple Choice

Complex trophic relationships in an ecological pyramid.

• Food Chain

• Food Web

• Abiotic Factor
